Description

Apparatus for supporting materials}

The present invention relates to a material support device for supporting a plurality of materials to be added to the treatment solution quickly, safely and continuously when the material is precipitated in the treatment solution, for example, to remove the plating layer.

The plated material is a product made excellent in corrosion resistance and paintability compared to the general material, such a plated material may require a mechanical test for the characteristics and analysis of the material according to the molding process.

Tensile test is the most basic mechanical test for grasping the mechanical properties of metal materials such as steel products, and for this purpose, a tensile test specimen of a certain standard is manufactured.

In the case of a plated material, the tensile test is carried out after removing the plated layer from the tensile test piece at all times or after removing the plated layer having the corresponding thickness (see Japanese Industrial Standard JIS G3302). Thus, by removing the plating layer of the surface, it is possible to analyze the difference in the properties and tensile strength before and after plating of the material.

Removal of the plating layer is carried out through a number of methods, it is usually removed by precipitating the specimen in a treatment solution such as hydrochloric acid. However, in this case, there is a problem that the test itself is considerably delayed because it takes a long time from removing the plating layer from the specimen.

In addition, the plating layer should be removed uniformly and cleanly on both sides of the specimen. If the plating layer is unevenly and incompletely removed during the removal process, it may be necessary to repeat the processing of the material, the removal of the plating layer, and the tensile test due to the variation in the quality of the test and the reliability. Losing a lot of time and money adds up. In addition, there is a high risk of a safety accident because an operator comes into contact with a strongly acidic treatment solution, for example, during the process of taking out the specimen from the treatment solution.

This bath can be made of a corrosion resistant material such as acrylic, PVC, etc., which is resistant to corrosion. In the solution tank, the rotating hole 15 is formed in the one side wall 11 and the other side wall 12 which face each other, respectively.

The rotating hole 15 may be formed in the form of a U-shaped groove or a through hole, and a bushing or a bearing may be added to the rotating hole. The rotating hole allows the frame 20 to be rotatably supported while being seated.

On the outer surface of one side wall 11 of the solution tank 10 may be provided with a first support portion 16 for installing the rotary drive means 30 to be described later at a predetermined height. The first support part may be made of a metal or plastic material such as steel as a substantially plate-shaped member, and may be fixed to one wall of the solution bath.

In addition, a second support part 17 may be provided adjacent to the wall 13 connecting the one wall 11 and the other wall 12 of the solution tank 10, and the gas described later by the second support part may be provided. The injection unit 40 may be supported. The second support portion may have a shape that is bent in a substantially 'L' shape and may be made of a metal or plastic material such as steel and installed adjacent to the solution tank.

The frame 20 is a rod or column shaped member having a predetermined length having a cross-sectional shape of approximately polygonal, circular or elliptical shape. This frame can also be made of a corrosion resistant material, such as acrylic, PVC, etc., which is resistant to corrosion.

The frame 20 is disposed in parallel with the longitudinal direction of the solution tank 10, the rotary shaft 21, which will be described later is inserted into the rotary hole 15 of the solution tank, so that the frame is one wall 11 and the other wall of the solution tank It can be laid over while extending between (12).

In the frame 20, a plurality of through holes 22 may be formed on side surfaces facing each other. A plurality of through holes formed on one side are spaced apart from each other along the longitudinal direction of the frame, each through hole may be formed in a substantially polygonal or oval shape.

For example, when the frame 20 has a rectangular cross-sectional shape as shown in FIG. 1 or FIG. 2, the through hole 22 formed in the upper first surface of the frame and the through hole formed in the lower second surface of the frame 20. May be aligned in communication with each other. In addition, the through holes 22 formed on the left third surface of the frame and the through holes formed on the right fourth surface may be aligned to communicate with each other.

Here, the distance between the through-holes 22 formed in the first surface or the second surface at one end or the other end located at the longitudinal end of the frame 20, and the penetration formed in the third or fourth surface at the one end The distances between the balls 22 are different from each other. That is, the alignment relationship between the through holes of the first and second surfaces and the alignment relationship between the through holes of the third and fourth surfaces should be arranged so as not to interfere with each other.

Rotating shafts 21 may be fixedly coupled to one end face and the other end face positioned at both ends of the frame 20 in the longitudinal direction, respectively. The first gear part 23, such as a bevel gear or a worm wheel, may be formed on the rotary shaft, but the shape of the first gear part is not necessarily limited thereto. The rotating shaft and the first gear portion may be made of a rigid material such as metal or plastic such as steel.

When the rotating hole 15 of the solution tank 10 is in the form of a through hole, the rotating shaft 21 that can be assembled is provided, so that the frame 20 can be installed to span the solution tank, and the frame can be separated from the solution tank. It becomes possible.

The plurality of mounting portions 25 may be installed to connect the through holes 22 formed on side surfaces of the frame 20 facing each other. The mounting portion includes, for example, a pin member 26 extending between the through holes 22 formed in the first and second surfaces of the frame 20 and inserted through the frame; It may include a magnet portion 27 provided to extend in a direction perpendicular to the longitudinal direction of the pin member at both ends of the pin member.

The cross section of the pin member 26 is formed in a substantially polygonal or elliptical shape corresponding to the through hole 22 so that the pin member 26 can be shaped to the through hole and at the same time prevent the turning or flow of the pin member in the through hole. . In addition, the pin member should be longer than the distance between the through-holes formed on the side facing each other, that is, the length in the width direction or the thickness direction of the frame 20.

At least one material 1 is attached to both sides of the mounting portion so that the mounting portion penetrates the frame and is upright in an I-shape. For example, the magnet portion of the mounting portion adjacent to the through hole 22 of the upper first surface is at least The magnetic part which is in contact with the first surface of the frame with one material attached, and adjacent to the through hole of the lower second surface opposite to the material, has a self-weight of the mounting portion and a load of at least one material attached to the magnet portion. It protrudes by a predetermined distance away from the second surface of the frame while being suspended by the pin member.

Thus, the raw material 1 attached to the magnet part 27 of the mounting part 25 which protrudes below from the frame 20 can be made to a suitable depth, and is easy even when a small amount of process solution is accommodated in the solution tank 10. FIG. Can be immersed in the treatment solution.

Furthermore, since the material can be attached and supported by the mounting portions 25 at both ends of the material 1, the material is stably attached and supported with respect to the frame 20. In addition, only a narrow area at each end of the material comes into contact with the magnet portion 27 of the mounting portion, so that the unprocessed surface area can be minimized due to the inaccessible treatment solution from the material. The plated layer can be removed uniformly and cleanly.

The rotation driving means 30 includes a drive part 31 provided on the first support part 16; A drive shaft 32 connected to the drive section; And a second gear portion 33 formed on the driving shaft and engaged with the first gear portion 23 of the rotation shaft 21.

As the driving unit 31, a motor that provides a rotational force may be employed. The drive shaft 32 can be connected directly or indirectly to the motor shaft of this motor.

A second gear portion 33 may be formed on at least a portion of the drive shaft 32. When the first gear portion of the rotating shaft 21 is a bevel gear, the second gear portion is a bevel gear, and the first gear portion is a worm wheel. In this case, the second gear portion may be formed of a worm. 1 and 2 illustrate a worm wheel and a worm. However, the forms of the first gear portion and the second gear portion are not necessarily limited to these examples.

The bearing portion 34 is connected to an end portion of the drive shaft 31 to support smooth rotation of the drive shaft.

As the driving shaft 32 rotates through the operation of the driving unit 31, and as a result, the second gear unit 33 rotates, the first gear unit 23 engaged with the second gear unit rotates to rotate the frame 20. In a predetermined direction, it is possible to rotate repeatedly with a predetermined time difference.

In addition, the material support device according to an embodiment of the present invention by spraying a gas toward the material 1 attached to the mounting portion 25 of the frame 20, to remove the treatment solution remaining on the surface of the material It may include a gas injection unit 40.

The gas injection unit 40 may include a spray pipe 41 supported by the second support unit 17; And it may include a supply pipe 42 for connecting between the injection pipe and a gas supply source (not shown). For example, a gas such as air or nitrogen may be injected from the injection pipe of the gas injection unit.

The injection pipe 41 is a thin and long pipe member having a hollow portion therein, and a plurality of nozzle holes 43 may be formed on one side at regular intervals along its longitudinal direction. The injection pipe is installed adjacent to the wall 13 connecting one wall 11 and the other wall 12 of the frame so as to be parallel to the longitudinal direction of the frame 20 or the solution tank 10. In addition, the injection pipe is preferably located slightly higher than the frame so as not to interfere with the rotational operation of the frame.

One end of the supply pipe 42 is connected to the injection pipe 41, and supplies a gas of a predetermined pressure supplied from the gas supply source to the injection pipe and the nozzle hole 43.

The plurality of nozzle holes 43 may be positioned toward the mounting portion 25 and the material attached to the magnet portion 27, which are floated from the processing solution due to the rotation of the frame 20 after being immersed in the processing solution. Therefore, the nozzle hole may be drilled in the normal direction or the diagonal direction at the bottom of the injection pipe 41.

By the self-weight of the gas and the processing solution of a predetermined pressure injected from the plurality of nozzle holes 43, the processing solution remaining in the raw material 1 can be removed to return to the solution tank 10.

Hereinafter, the operation of the material support device according to an embodiment of the present invention configured as described above will be briefly described with reference to the drawings. For convenience of explanation, the case where the material is precipitated in the treatment solution using the material support device of the present invention for removal of the plating layer will be described as an example, but the use example of the material support device according to the present invention is not necessarily limited thereto. In addition, although the case where the frame has a rectangular cross-sectional shape as illustrated in FIG. 1 or FIG. 2 is described as an example, the shape of the frame is not necessarily limited thereto.

First, a treatment solution such as hydrochloric acid is contained in a predetermined amount in the solution tank 10.

The frame 20 extends between one wall 11 and the other wall 12 of the solution bath 10 and extends therebetween, and the magnet portion of the mounting portion 25 on the upper first surface of the frame exposed from the solution bath ( At least one material 1 is attached to 27. FIG. 1 shows an example in which a plurality of magnet parts are provided on an upper first surface and three materials are attached side by side along the longitudinal direction of the frame.

At this time, the magnet portion 27 of the mounting portion 25 adjacent to the through hole 22 of the upper first surface is in contact with the first surface of the frame 20 with at least one material 1 attached thereto.

The drive shaft 32 is rotated by operating the drive unit 31 of the rotary drive means 30, and as a result, the second gear unit 33 rotates, whereby the first gear unit 23 engaged with the second gear unit is rotated. The frame 20 is rotated in a predetermined direction, for example, by a predetermined time difference by 90 degrees clockwise in FIG. 1.

By this rotation, the first left third surface of the frame 20 is moved to the upper position to be exposed from the solution bath 10. As a result, at least one material can be attached to the magnet portion 27 of the mounting portion 25 on the third surface of the frame.

The frame 20 is repeatedly rotated by 90 degrees in a predetermined direction with a predetermined time difference.

By this further rotation, the first lower second surface of the frame 20 moves to the upper position and the first upper first surface moves to the lower position, i.e., the upside down reverse occurs. At least one material 1 may be attached to the magnet portion 27 of the mounting portion 25 on the second surface of the frame exposed from the solution tank 10.

In this way, the magnet portion 27 of the mounting portion 25 adjacent to the through hole 22 of the second surface comes into contact with the second surface of the frame 20 with at least one material 1 attached thereto. The mounting portions, each of which has a material attached thereto, stand up substantially in an I-shape through the frame.

At the same time, the magnet part 27 adjacent to the through hole 22 on the opposite side of the pin member 26 is caused by the weight of the mounting part 25 and the load of at least one material 1 attached to the magnet part. While hanging on, it protrudes by a distance away from the first surface of the frame 20.

Thereby, the raw material 1 attached to the magnet part 27 of the mounting part 25 which protruded below from the frame 20 can be immersed in the process solution of the solution tank 10. FIG. As the material is immersed in the processing solution for a set time, the plating layers on both sides of the material can be removed uniformly and cleanly.

When the set time has elapsed, the drive shaft 32 is rotated by activating the drive unit 31 of the rotation driving means 30. As a result, the second gear unit 33 rotates, thereby engaging the first gear unit engaged with the second gear unit. As the gear unit 23 rotates, the frame 20 may be rotated by 90 degrees in a predetermined direction.

By this rotation, the first right fourth surface of the frame 20 is moved to the upper position to be exposed from the solution tank 10. Thereby, the at least one raw material 1 can be repeatedly attached to the magnet part 27 of the mounting part 25 in the 4th surface of a frame.

In this way, the magnet portion 27 of the mounting portion 25 adjacent to the through hole 22 of the fourth surface comes into contact with the fourth surface of the frame 20 with at least one material 1 attached thereto. The mounting portions, each of which has a material attached thereto, stand up substantially in an I-shape through the frame.

At the same time, the magnet part 27 adjacent to the through hole 22 of the third surface opposite to the pin member 26 is caused by the weight of the mounting part 25 and the load of at least one material 1 attached to the magnet part. While hanging on, it protrudes by a distance away from the first surface of the frame 20.

The mounting portions 25 disposed between the through holes 22 of the first and second surfaces and the mounting portions disposed between the through holes of the third and fourth surfaces interfere with each other when moving by self weight and load. It doesn't work.

Thereby, the raw material 1 attached to the magnet part 27 of the mounting part 25 which protruded below from the frame 20 can be immersed in the process solution of the solution tank 10. FIG. By the material being immersed in the processing solution for a set time, the plating layers on both sides of the material can be removed uniformly and cleanly.

On the other hand, the raw material 1 attached to the magnet portion 27 of the mounting portion 25 which floats from the processing solution laterally through the rotation of the frame 20, for example, to the left in FIG. The treatment solution remaining on the surface can be removed by the self-weight of the gas and the treatment solution of the predetermined pressure injected from The removed treatment solution may be directed to return to solution bath 10.

Again, when the set time has elapsed and the frame 20 is rotated by 90 degrees in a constant direction by the rotation driving means 30, the material 1, as well as the plated layer, from which the treatment solution has been removed is removed from the solution tank 10. Exposed. These materials can be separated from the magnet portion 27 of the mounting portion 25, and the above-described process can be continuously and repeatedly carried out through the attachment of new materials.

If necessary, after the attachment of the material 1 to the frame 20 is completed by rotation without completing the attachment of the material in a state in which the frame is separated from the solution tank 10, the frame is mounted in the solution tank and rotated. While removing the plating layer and the treatment solution may be performed.

As described above, according to the present invention, it is possible to support a plurality of materials so that they can be added to the treatment solution repeatedly, safely and continuously, thereby reducing the time and cost used for preparing the test, for example. As a result, the worker is prevented from coming into contact with the treatment solution, thereby eliminating the risk of safety accidents and reducing the amount of the treatment solution, thereby improving the environmental pollution.

In addition, when the present invention is used for the test, the reliability of the test is increased, and there is an effect that can ultimately contribute to the improvement of the quality of the product.
